Vgen > 10 V (any phase).
“Still engine” conditions
Engine speed (RPM) <= 1 RPM
AI: Oil press < Starting POil
Generator voltage < 10V (all phases)
When the engine was running before and all above conditions are fulfilled, additional 2s delay is
necessary to confirm “still engine”.
When any engine running conditions are appeared on still engine than the Wrn Stop Fail is activated
with following delay:
- for generator voltage < 50% of nominal voltage, Wrn Stop Fail has delay 1s
- for generator voltage > 50% of nominal voltage, Wrn Stop Fail has delay 200ms
- for oil pressure > starting oil pressure, Wrn Stop Fail has delay 1s
- for detected RPM, there is no delay.
“Stop engine”conditions
If no engine running conditions are validated than the controller will wait extra 10s before leaving the
Machine state Stop and then it will release the Binary output Stop solenoid.

When the total time of stopping will exceed setpoint Stop time (in Engine Params) than the Stop fail
warning and related binary outputs are activated. The controller will continuously try to stop the
engine.
